   CELQVGHP      000000002A15F330  +0000000000000000   CELQLIB
   _dwarf_get_alloc

   _dwarf_string_convert_cs
                 000000002C078538  +00000000000000AC   CDAEQED

   CEEOSIGG      000000002A0B81E0  +0000000000001430   CELQLIB
  
  storage requested via CDA api dwarf_linesrc() was not being
  freed, and therefore led to the above reported leak.
